Board meetings dynamics and information diffusion
No full textResearch Question/Issue: This paper provides novel evidence on the dynamics of board meetings and the economic value of their decisions. We exploit a unique regu- latory requirement of the Italian Stock Exchange that mandates the publication of board meeting minutes when the board votes on “price sensitive” matters to analyze detailed data about directors' participation, discussions, voting, and the dissemination of their decisions to the market.
Research Findings/Insights: In a large, multiyear sample of board meeting minutes, we show previously unavailable patterns of board meetings participation and discus- sion and highlight the moderating role of key governance mechanisms that shed novel light on the effectiveness of boards. Looking at the economic value of board meetings, we document significant delays in the diffusion of information in the mar- ket that may be indicative of information leakage.
Theoretical/Academic Implications: We contribute to the theoretical discussion about the role of boards. Our results are consistent with a supervisory approach model of boards where consensus is high and dissent is costly. However, they cast doubt on the efficacy of boards as a counterbalancing mechanism to the power of executives.
Practitioner/Policy Implications: Boards have grown in size and become increasingly complex. This study documents the actual discussion, participation, and voting dynamics of board meetings and provides evidence on the diffusion of information to market participants, which is valuable in the design of efficient corporate governance mechanisms
Women board members’ impact on ESG disclosure with environment and social dimensions. Evidence from the European banking sector
No full textPurpose – This study aims to investigate the relationship between banks’ board structure and sustainability performance.
Design/methodology/approach – The empirical quantitative paper covers a sample of 35 European banks that are listed at the EUROSTOXX 600. Regression analysis techniques were used in the analyses. Findings – Results indicate that board size, women ratio and independent directors ratio on board are positively and significantly related to environmental social governance (ESG), E and S disclosure scores. Also, we find that ESG disclosure is related to bank profitability.
Practical implications – Findings have implications for both policymakers and practitioners (bankers and investors). Large bank boards, which have women and independent members, could perform better in terms of ESG disclosure. The results also show that large banks and banks with high borrowing care more about sustainability. For banks to reach resources, they should perform well in terms of sustainability disclosure to their stakeholders.
Social implications – Banks should observe academic findings on corporate governance (CG) practices, which lead to a better ESG disclosure to structure their CG to improve at the best their disclosure policies: they should prefer larger boards with a high level of women and independence. In addition, we attach importance to the ESG performance of the banking sector due to its fund transfer functions. Banks transfer the deposits they collect to those in need of funds as loans. For this reason, it is important to which sector and which business they give credit. The importance of banks on ESG and their adoption of sustainability dimensions also affect their credit decisions
Investigation of the Weather Conditions During the Collapse of the Morandi Bridge in Genoa on 14 August 2018 Using Field Observations and WRF Model
No full textOn 14 August 2018, Morandi Bridge in Genoa, Italy, collapsed to the ground that was 40 m below. This tragedy killed 43 people. Preliminary investigations indicated poor design, questionable building practices, and insufficient maintenance—or a combination of these factors—as a possible cause of the collapse. However, around the collapse time, a thunderstorm associated with strong winds, lightning, and rain also developed over the city. While it is unclear if this thunderstorm played a role in the collapse, the present study examines the weather conditions before and during the bridge collapse. The study particularly focuses on the analysis of a downburst that was observed around the collapse time and a few kilometers away from the bridge. Direct and remote sensing measurements are used to describe the evolution of the thunderstorm during its approached from the sea to the city. The Doppler lidar measurements allowed the reconstruction of the gust front shape and the evaluation of its displacement velocity of 6.6 m s−1 towards the lidar. The Weather Research and Forecasting simulations highlighted that it is still challenging to forecast localized thunderstorms with operational setups. The study has shown that assimilation of radar reflectivity improves the timing and reconstruction of the gust front observed by local measurements
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

We examined students in a college course who learned about one scholar's ideas through watching an audiovisual TV interview (i.e., visible author format) and about another scholar's ideas through reading a formal text description (i.e., invisible author format). For the invisible author, native language speakers scored significantly higher than the non-native language speakers on a corresponding exam question (i.e., a cognitive measure), generated more words on the exam question (i.e., a motivational measure), and mentioned the author's name more often in answering the exam question (i.e., an affective measure). For the visible author, the groups did not differ on any of these measures. These findings provide evidence for the idea that making the author visible through audiovisual TV interviews can eliminate the learning gap between native and non-native language speakers. 3 Universities around the world serve students who are non-native speakers of th
